138 Array of integers with default pattern for certain triggers.

154 Maximum LED supply current in microamperes. This property can be made
157 For flash LED controllers with configurable current this property is
158 mandatory for the LEDs in the non-flash modes (e.g. torch or indicator).
160 max-brightness:
163 property is not required. This property is used to set a software limit.
